Today's day is so happy, Han Tuo is like a doping, even talking and making trouble, hands, dancing, feet, walking, the house can't fit him, and he has been playing until more than nine o'clock in the evening and refuses to leave, saying that he wants to watch the big color TV with Xiao Ji for a night.

The new big color TV,It does have a lot of attraction for children,Xiao Ji said that he wanted to watch TV with Han Tuo's brother for a night,But she is a child after all,Just ten o'clock is already sleepy,Can't open your eyes,Still watching TV there。

Li Lanfang and Han Tuo looked at Xiao Ji's cute appearance and smiled greatly, and Zhao Yunfei also had a smile on his face.

Xiao Ji grinned and wanted to laugh but was too sleepy to laugh, and then lay on the kang and fell asleep regardless of it.

Zhao Yunfei gave Xiao Ji a pillow and covered it with a sheet, Li Lanfang got up to go home, she wanted to linger with Zhao Yunfei tonight, but Han Tuo, the kid, refused to leave, and he was sleepy, so he had to go back.

Han Tuo wanted to live in Zhao Yunfei's house, and Zhao Yunfei thought that he would practice "True Dragon Jue" tonight, and Han Tuo would be very inconvenient here.

For him, the dragon slaying knife and the "True Dragon Technique" are very secret things, and they must not be let others know, and one more person knows about it, even Han Tuo can't do it, and he has already told Han Tuo that the rusty sword dug up by digging voles was sold by him for scrap iron, Han Tuo never doubted what Zhao Yunfei said, of course he believed it.

Zhao Yunfei didn't mean to deceive his friends, but deep down he really felt that these two things were too strange, in case the news was revealed, he didn't know what kind of trouble it would cause, and with his current ability, he might not be able to deal with those unknown risks.

He once read a sentence in a book that the great scientist Newton said: I can calculate the trajectory of celestial bodies, but I can't calculate the greed of human nature! -- He was impressed by this statement.

Therefore, in order to keep it secret and to cultivate the True Dragon Recipe according to the plan, Zhao Yunfei persuaded Han Tuo to go home and let him go home and sleep well, and go to the town together early tomorrow morning.

Sending Li Lanfang and Han Tuo out of the door and plugging in the iron door, Zhao Yunfei was not in a hurry to return to the house, but walked around the courtyard casually for a while.

The night in the mountain village is quiet and serene, looking up at the night sky, the stars are shining, the Milky Way is vast, "how many secrets are hidden there!" Whenever Zhao Yunfei looked up at the night sky like this, he couldn't help but think like this.

Taking a few deep breaths of fresh and slightly cool air, Zhao Yunfei felt that his spirit had recovered a lot, after all, he had been busy all day.

When he returned to the house, he saw Xiao Ji lying on the kang, his arms stretched out, sleeping soundly and deeply, Zhao Yunfei extinguished the light, took off his shoes and put on the kang, took off his clothes, only wore a pair of boxer trousers, sat cross-legged on the inside of the kang, adjusted his breathing first, and then thought about "True Dragon Jue" in his mind.

Although Zhao Yunfei is still a little skeptical about this so-called "True Dragon Jue", he has a very good advantage, that is, no matter what it is, as long as he decides to do it, he will definitely treat it with an extremely serious attitude, and he has always had a beginning and an end, a beginning and an end.

Zhao Yunfei pondered carefully.

The first half of "True Dragon Jue" seems to explain why dragons can fly in the sky without wings, and they do not have gills like fish breathing in water, but they can dive in the sea. Dragons are not divine ......", the first sentence says "dragons are gods", but the fourth sentence says "dragons are not divine objects", isn't this inconsistent?

Zhao Yunfei pondered again, and immediately understood that the first sentence "The dragon is a god" is because it "has no wings to soar too empty, and cheeks without gills to dive into the nine abysses", which is called a god by people.

Zhao Yunfei thought about it, not to mention that in ancient times when science and technology were not developed, even now, if an animal that could fly without wings suddenly appeared in the sky, it would definitely be regarded as a god by many people, even if it was a pig that flew - people always deified a phenomenon that they were not capable of explaining.

"It seems that there may be some truth in this "True Dragon Formula"!" Zhao Yunfei frowned slightly, at this time his attitude towards the "True Dragon Jue" was much more solemn than before.

Then consider the following sentences.

The fourth sentence says, "Dragons are not gods," which is a clear telling of the practitioner that dragons are not gods.

"Gai Qi is good at yin and yang qi, refining it into electricity, and hiding it in the acupoints and veins around the body", what is "yin and yang two qi"? Is it air? How do you divide yin and yang into air?

Zhao Yunfei thought about it for a long time, but he didn't understand what the two qi of yin and yang were.

Fortunately, he is not a person who drills the horns of the bull, and he really doesn't think about what he can't understand, so it is too much time, it is better to combine practice in the process of practicing while thinking, practice to get true knowledge - he has long had a practical understanding of this sentence, when he began to learn to farm, he felt that he was young, he didn't understand, he didn't understand, there were problems everywhere, but when he really started to do it, all the problems didn't exist, it can be seen that doing everything is the same, the most important thing is action, The end result of the fantasy is that nothing can be accomplished.

"Refining into electricity", is the "electricity" mentioned here the electricity that can make the light bulb shine and heat?

Zhao Yunfei knows that many concepts in ancient times are different from modern ones, and modern times continue to use ancient words but give them new meanings. He suddenly thought of the green garden that left a text and a poem, and he didn't know how this green garden explained the word "electricity"?

Zhao Yunfei shook his head.

Judging from the words left by Lu Yuansuo, especially the poem, there is no doubt that it must be the ancients, maybe it was the Qing Dynasty, maybe it was the Ming Dynasty, and it may even be as far as the Tang and Song dynasties, but no matter which dynasty in ancient times, the domestic society at that time had not yet established a scientific system, and even did not know what science was, I am afraid that this Green Garden would not understand what "electricity" was.

Judging from the traditional Chinese glyph of electricity, the top is a rain prefix, and the bottom is the current simplified electric character, which shows that the ancients' understanding of electricity was limited to lightning when it rained on a cloudy day.

In modern times, electricity is not so mysterious, although Zhao Yunfei is only a student who has just graduated from primary school, but in the textbooks of primary school, the basic principles of electricity have been introduced, besides, Zhao Yunfei because of premature assumption of family responsibilities, his knowledge of all aspects is much richer than that of ordinary children, electricity is the most important energy source in daily life, and his contact with electricity is naturally indispensable.

As for how the "dragon" uses the two qi of yin and yang to refine into electricity, Zhao Yunfei didn't think about it, he knew that even if he wanted to break his head, he couldn't figure out these two sentences, maybe the "dragon" was born with this function, just like a spider can spin silk and form a web, and a bat can use sound waves to locate it.

"Then he spit fire and smoke, go to the sky and enter the sea, ride the rain and the wind, and transform into infinite", Zhao Yunfei sat there and nodded lightly, thinking to himself, it turns out that this is the case, the dragon has such a ability because it can generate electricity on its own body, but that is not right, even if it is charged on its body, it can't fly? It can't have a motor or a propeller on it...... As for "diving into the abyss without gills", it is not difficult to do, there are many animals in the ocean that live in the sea without gills, even people, if their lung capacity is large enough, they can stay in the water for a long time......
